RAM Upgrade Help (Ramdisk, Timings and More)

So I'm building a new computer, and I'm going to go with the cheaper 6 core i7 CPU instead of the generic 2600k. This CPU supports quad channel RAM and I'm trying to figure out what would be the best option overall for my choice of RAM. (Yes, I'll be doing a lot of HD video editing/encoding)

A simple question to solve all this: What would the speed advantage of a Ramdisk be over 2 SSDs (500MB/s+ Read 400MB/s+ Write each) in RAID 0? I'm assuming for just about everything, especially video editing, the CPU would bottleneck long before either drive setup, but I've yet to use either so I could be wrong. If there's next to no difference, I'll just get 2 sets of Blue and save a bit, as I don't see it being possible for me to ever use just 30% of 32GB.

The Red isn't really an option due to it's price, but it does raise a question: out of the above, which is truly the "fastest"? I've done the math and even with the higher clock speed, the slower timings cause it to perform less calculations overall. I notice that in general, as the Mhz go up, so do the timings, which cause it to perform slower and run hotter. Am I missing something here, or what?

Finally, the KB RAM seems too good to be true. 8GB sticks running 9's at stock 1.5v (like every other set listed) for dirt cheap. What's the catch? They do come with low profile heat spreaders instead of the much better Corsair heatsinks, but I have RAM cooling fans, so they seem better, as I'm pretty sure the fans won't even fit over the Corsair units.

That's all I can think of for now, but I'm sure I'll have more to add later. I thank you in advance for your replies

EDIT: Forgot about another set of KB RAM, 8GB sticks - 1600Mhz - 10-10-10-27 but come with non low profile heatsinks. Slightly cheaper than the above set but would they be a worse buy because they're slower and wouldn't be fan cooled?

The real question here is why in the world do you want to spend that much money on ram when you said it yourself, you don't even need half as much?

I'd cut the ram in half, or less depending on what you want to do with it and get the faster i7 cpu, you will appreciate it more in the long run.

That or get less ram, but faster memory.

But the main point here is, what are you goals with this PC? Timings, bandwidth, ram amount, cpu speed all play different roles here, so depending on what you are doing, you may benefit from one setup over the other.

On that note, the only i7 based cpu less than a 2600k is a 2600, which is not what you want to get over the k model if overclocking is a concern.
